"Be it known that l, JOHN P. Reinheim, a citizen of the United States,residing at Lorain, 'in the county of Lorain and State 5 o :(hio, hare.invented a certain new `and useful Improvement Iin Gas-ValveStructures, of whichthe following is a full, clear, and exactdescription. j This invention relates to a gas regulating .10 valve foruse in connection with gas burners. The object ot the-invention is toprovide a 'burner in which the How oit gas is controlled by aninsideadjustable member which is easily accessible for regulatingpurposes. i i I Reference should be hadto the accompanying drawingforming a part of ythis specification in which the ligure is a sectionaleleva-` tion.

Referring to the 'drawing7 1 indicates a body "portionwhich has anextension l2 which `isthreaded, as indicated at 3, thisportion beingadapted toi-connection yto `the feed pipe o a stove,`or the feedjgas`pipe of any construction in connection with which the herein describeddevice may be used. dlherc is also an rextension at right angles to theextension l2 whichis indicated 'at 4. This efr-tension is hollow,fand atits outer end is `providedwith an Aexit opening `The end of theextension 4 terminates inl aconical slanting portion 67 which may .begenerally 'speaking conical in shape, and the opening 5 is atthe upperor end `portion of the slanting parte. Upon the `outer surface of theextension l there are threads 7, and upon these threads there is la nut8. This nut `may be adjusted to any desired position upon the thread 7,thereby determining the dis- 10` tance which the extension e will extendinside ot the `mixer of the usual burner.

There is an axial passageway 9 which extends through the extension 2 andit communicates with an enlarged chamber 10 which is formed in themember 1. The member l and the extension l are hollow, and threaded intoan opening 1a at the lower` portion of the body 1 is a threaded barrelportion 11. Extending from this barrel portion is a hollow tubular part12 which is provided withopenings 13, at a portion thereof so that theycommunicate with the chamber 10, and gas which passes through thepassageway 9 and to the chamber 10 will,

i5 at une rcp thereof, and ,with a plurality of openings 116 for-med inthe conical wall portions j The member 11 `and the tubular member 12 arecapable of adjustment within the member 1, this adjustment beingelleo-ted by inea-ns of a knurled 'Ahead portion lf? which 1s formed asa part of or `connected to the barrel portion 11. A 'lock nut l1-8 isthreaded upon the 4threads ofthe .outer-surface of the barrel portionl1, and is adapted to engage with the `lower end oit the body portion-lso as to 'hold the barrel part 11 and the hollow tubular portion 12 inany adjusted position. Whenthe tubular -meinber 12 *is extended to itsnmost outward position the conical portion will entend up into theopening and the conical walls of the member 12 will engage w-iththeedgeofrthe opening l5 so that gas passing through the tubular member 12can find exitfonly through the opening 15. r

lf `it be desired-torv supply more gasthrough moved linwardly in the4manner before ydescribed, .so that the conical 4wall 'portion 14 is `outAof engagement with the lower Vorinner edge `of fthe opening 5, andrunder-these conditions .gas may pass through fthe ope`nings 16 and`around the 4outside of the Lconi-l cal portion 11i, andl through the4orifice The extent to which gas may thus flow will, of course, dependupon the clearance between the conical portion 14C and the inner edge ofthe orifice l.

It will be noted that the adjustable tubular member 12 will at its outerend be guided by theinner walls of the extension i so that theco-operation between the conical portion 14 and the outlet 5 will beassured.

By the structure which has just been described the member necessary tobe moved in effecting an adjustment for the quantity of gas to bedelivered, is readily accessible being entirely beyond the pipe whichfeeds gas through the valve structure.

The arrangement of parts which has been described also has the advantageof increa`sing the flow of gas to its maximum capacity because of thetact that the orifice in the the orifice 15 then the tubular member12`is for entraining air as it passes into the mixer of a burner.

Having described my invention, l claim 1. A gas valve comprising atubular body having at one end a tapering wall provided with an axialvdischarge opening and a gas inlet adjacent the opposite end, a tubularmember within said body and adjustable longitudinally thereof, saidtubular inember being of less diameter externally than i, the internaldiameter of the body whereby an annular passageway from the inlet to thedischarge opening is provided upon the exterior of the tubular member,said tubular member having openings in the wall thereof establishingcommunication with said passageway and a tapering end portion adapted tobe moved into engagement with the discharge end of the body to closesaid annular passageway, said end portion of the tubular member havingan axial opening of less diameter than the discharge opening of thebody.

2. A gas valve comprising a tubular body having an end wall providedwith a conical Y inner surface and an axial discharge opening, said bodyhaving a lateral gas inlet, a tubular member within said body andadjustable longitudinally thereof, said tubular member being of lessdiameter than the tubular body whereby an annular passage i way isformed between said tubular membei' and tubular body, said tubularmember having a closed lower end which fits within the'lower end of thebody and forms a closure therefor, said tubular member having openingscommunicating with the passageway and a conical end portion adapted toengage in the discharge opening of the body 3. A valve comprising a bodyportion having an extension with a gas passage therethrough and capableof being connected with a gas feed pipe, said body portion having anopening at right angles to the extension just mentioned, and having ahollow extension which is in alignment with the opening in the bodyportion just mentioned, said extension at its upper end having aslanting wall portion and an outlet orifice which is centrally disposedwith respect to said extension, a movable tubular member within saidhollow extension said tubular member being guided in its movement by theinner walls of said extension of the body portion said tubular member atits outer end having slaiitiiig walls, with an orifice which is in axialalignment with the outlet orifice before mentioned, the said slantingwalls having openings which are not in alignment, said tubular member atthe end thereof being provided with openings which communicate with thegas passageway in the first mentioned extension for the body portion', abarrel portion connected with the tubular member said barrel portionhaving a threaded exterior and-- which it co-operates to control thepassageof gas therethrough.

ln testimony whereof, I hereunto affix my signature.
